INSTRUMENT FOR MEDICATING THE MIDDLE EAR.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed May 15, 1907. Serial No. 373,827.

To all whom it may concern:

Be it known that I, J OIIN A. GAULT, a citizen of the United States,residing at Lancaster, in the county of Grant and State of W'isconsin,have invented certain new and useful Improvements in Instruments forMedicating the Middle Ear, of which the following is a specification.

My invention relates to improvements in devices for treating diseases ofthe middleear and it differs in detail from my applicationconcurrentlyfiled Serial Numb er 373,826, which invention is especiallyconstructed for the treatment of another organ of the body. Its objectsare to provide for readily carrying out that end more especially by theuse of medicaments volatilized and delivering the latter into the middleear; and to accomplish the same in a simple, economic and effectivemanner.

Said invention consists of certain features or instrumentalitiessubstantially as hereinafter fully disclosed and claimed.

In the accompanying drawing Figure l is a side view showing the parts ofthe same as assembled for actual use. Fig. 2 is a like view showing theparts of the device as disassembled. Fig. 3 is a cross-section throughthe rece tacle for application to the ear.

The n meral 3 represents a tube and lis a flaring mouth integral withone end of the tube and adapted to receive the ear. A pneumatic rubbercushion 2 is placed over the open end of the mouth 1 to form a gas tightjoint at the point of contact between the mouth and the patients headabout the ear. Into the tube 3 a cup 4 is adapted to be inserted forreceiving and containing the medicarnents, which latter are suitablyvolatilized and which are then delivered into the middle ear and throughany perforation of the ear drum which may have resulted from disease orfrom the surgeons knife. This cup is cylindrical in form to enter andfrictionally fit the end of the tube, and it preferably has a segment ofits surface removed, which leaves remaining the extension or elongation7 which has one fiat surface to prevent the medicament itself from beingcarried to the treated parts, which would prove disastrous, whilepermitting the advantageous release of the vapors arising from themedicaments after volatilization for delivery to said parts.

The outer end of this cup is flanged to limit its insertion in place inthe tube.

A spring arm 5 is suitably held by -a setscrew 6 on the tube 3 forattachment to the head, it being made of slidably connected sectionswhich render it extensible and conformable to heads of different sizes.

The medicament I preferably employ herein and which may be used eitherwith or without the device, is the gas arising from formaldehyde, andall mixtures and compounds thereof, with other medicines, drugs orsubstances,

I claim 1. A device as described, comprising a tube adapted forapplication to the human ear and having means for its attachment to thehead, and a cup or holder insertible into said tube, for the receptionof a medicament, and having a segment of its surface removed, theelongation or extension thus formed having a closed upper surface or topfor the purpose stated and yet adapted to allow of the delivery of thegas resulting from the volatilization of said medicament.

2. A device as described, comprising a flared pyramidal-like tube havingan extensible attaching means for application to the head, and a cup orholder insertible into said tube for'the reception of a medicament andhaving a segment of its surface removed, the elongation or extensionthus formed having a closed upper surface or top for the purpose statedand yet adapted to allow of the delivery of the gas resulting from thevolatilization of said medicament.

3. A device as described, comprisin a tube having one end flared ingeneral out ine longitudinally, it also being flared, in transversesection, upwardly from quite a contracted lower portion, means for theattachment of said tube to the head, and a cup or holder insertible intosaid tube for the reception of a medicament and having a segment of itssurface removed for the liberation of the gas resulting from thevolatilization of said medicament.

In testimony whereof I affix my signature, in presence of two witnesses.

JOHN A. GAULT.
